Don't risk the heartbreak of lost fish, and even damsels suffer in a tank break-in, though they may survive.
Set it up. Are you using live rock? Get a powerhead or a strong filter or better get both. Substrate? Aragonite is best. Plan for what you'd like to keep, set up your tank and cycle it first.
In about a 3 weeks, month you can add some hermit crabs and hardy fish, like the damsels (which are aggressive) or something like clownfish or firefish or dottybacks or wrasses or pseudochromis (prettier in my opinion) if you wait until things are very stable.
Go slow and think about what you want. It works out better in the end...
I lost a blue-green chromis to ich, and I think it was because my nirtites were just a tad too high. Although tuff fish, they can succumb too and stressing them by an uncycled tank is just mean.
